PROBLEM TO BE SOLVED: To provide a transmission for combine with a side clutch, which can be manufactured with less time and effort.SOLUTION: A transmission for a combine includes: a steering operation tool which can be manually operated a transmission shaft 55 supported by a mission case 13 a drive gear 57 provided in the transmission shaft 55 and rotated by drive power of an engine and a pair of right and left side clutches 60 provided in the transmission shaft 55, configured to individually connect the drive gear 57 to a pair of right and left moving devices, and to be selected between an engaged state that connects the drive gear 57 to the moving devices and a disengaged state that does not connect the drive gear 57 to the moving devices by the operation of the steering operation tool. The side clutch 60 includes a connection gear 62 that slides along a transmission shaft 55 and can be meshed with the drive gear 57 by the operation of the steering operation tool.COPYRIGHT: (C)2013,JPO&INPIT【課題】製作手間の掛かり難いサイドクラッチを備えたコンバインのトランスミッションを提供する。【解決手段】手動操作可能な操向操作具と、ミッションケース13に支持された伝動軸55と、伝動軸55に設けられてエンジンの駆動力によって回転する駆動ギア57と、伝動軸55に設けられると共に、駆動ギア57と左右一対の走行装置とを各別に連係可能であって、操向操作具の操作によって、駆動ギア57と走行装置とを連係するクラッチ入り状態と駆動ギア57と走行装置とを連係しないクラッチ切り状態とに切り換え操作される左右一対のサイドクラッチ60と、を備え、サイドクラッチ60に、操向操作具の操作によって伝動軸55に沿ってスライド移動して駆動ギア57と咬合可能な連係ギア62が備えられている。【選択図】図4
